I recommend using the latest version available, netCDF-4.1.2, and if you only 
want
netCDF-3 capabilities, build it with the configure option --disable-netcdf-4.  
Also
if you have no need for the OPeNDAP remote access client now built into the 
library
even for netCDF-3 data, you can also use the configure option --disable-dap.  
That
will get you all the bug fixes in netCDF-3.6.3 as well as others for netCDF-3 
that
are only available in the netCDF-4 source distribution.  The new version has 
been
extensively tested, and even builds easily on cygwin platforms.  Get it from 
here:
